of the intensifier surface by slowly opening the lens iris starting at the largest f-stop (f32
or f16) of the lens. Slowly open the lens iris and watch the image brightness, while
viewing live image on the monitor, until an optimum level of brightness is reached.
Do not expose the light-entrance window (the intensifier’s front surface) to strong light,
such as sun light, while operating or storing the intensifier. Bright light falling on the
light-entrance window of the image intensifier surface, even when the device is not
operating, can damage the image intensifier. Always store the camera head with an
appropriate body cap or lens and lens cap in place when not in use.
Operating the image intensifier while it is exposed to bright light (e.g. ambient room
illumination) will cause serious damage to the intensifier’s photocathode.
Always adjust the intensifier (and camera) while watching live image on the
monitor.
Switch the intensifier off when done with a recording or test. Avoid exposing the
light-entrance window of the intensifier to bright light while changing lenses
regardless of whether the intensifier is powered. The intensifier tube can be
damaged by excessive light with or without power on.
If a lens whose iris does not completely close is used, install a lens cap to avoid
exposing the intensifier to excessive light while not in use.
When installing the image-intensified camera on a microscope, make sure there is
no leakage of light from other than the microscope’s light source.
